  • Patent number: 11519349
    Abstract: A control system includes a first control device and a second control device. The second control device transmits, to the first control device, a resonance influence torque or a first motor rotation angle speed, and information acquisition timing, which is an acquisition timing of the first motor rotation angle speed. The first control device calculates an engine inertia torque based on an engine rotation angle speed. The first control device selects the resonance influence torque based on the first motor rotation angle speed acquired at a predetermined derivation timing, based on the received information acquisition timing, and derives, as an engine torque, a sum of the resonance influence torque and the engine inertia torque, calculated based on the engine rotation angle speed derived at the predetermined derivation timing.
